Lake Effect Snow Showers Possible Tonight

Jaris DingmanNE Ohio Primary Snowbelt

Flurries and light snow have come mostly to an end across northeast Ohio. A weak surface trough will cross the area this afternoon which will veer winds from the west this evening. The trough may provide a source of lift and westerly winds over the lake may lead to some lake effect snow showers in northern Geauga and Lake Counties.

There are numerous limiting factors with this lake effect setup including the best omega (vertical velocity) being below 800 mb and below the DGZ. Another limiting factor is a fair amount of wind sheer from the surface up to 700 mb. So any snow that develops should be very light and any accumulations should also be very light. Mesoscale models are suggesting the timing for snow to be from 7 pm tonight through 1 am Thursday. Outside of these areas should be dry.

Temperatures will range from 27 to 30 degrees while any snow falls. This will lead to any snow that falls to stick to pavement. Snow accumulations should be a dusting to an inch. One inch totals look unlikely, but not impossible. The highest totals should be in Ashtabula and Erie Counties.
